Abstract
A 59-year-old man was admitted to our hospital with severe abdominal pain and a high temperature. Abdominal-CT revealed a solid tumor about 8cm in diameter continuing to the small intestine. The laboratory data revealed marked elevation of WBC and CRP levels. An emergency operation was carried out under the diagnosis of peritonitis. Fistula formation was confirmed in the small intestine contiguous with the tumor. We performed a partial resection of the small intestine and sigmoid colon. The tumor was composed of solid and necrotizing regions. Histopathological findings showed that the tumor was composed of proliferative spindle-shaped cells. Because the tumor cells were positive for c-kit, we diagnosed the tumor as GIST of the small intestine. A case of perforated gastrointestinal stromal tumor of small intestine is herein described with a brief review of the literature.
